PUMP.

SPECIFICATION forming part of Letters Patent No. 394,699, dated December 18, 1888.

d Application filed September 20, 1888. Serial No. 285,867. (No model.)

T0 all 1071/0771/,2115 77mg/ cm1/136771,:

Be it known that I, WILLIAM KEAsT, of Russell Gulch, in the county of Gilpin and State of Colorado, have invented a new and Improved Pump, of which the following is a full, clear, and exact description.

This invention relates to improved valveoperating Inechanism to be applied to the suction-box of Iny new pump shown and described in Iny allowed application, Serial N 25,$92, tiled October 20, 1887.

Reference is to be had to the accompanying drawings, formingl a part of this specification, in which similar letters ot' reference indicato corresponding` parts in both the Iigures.

Figure l is a broken perspective view of the suction-box marked P in my said appli'- cation, showing my improved mechanism for operating' the valves to drain the pump; and Fig. 2 is a sectional elevation taken on linc a' of Fig. l.

The suction-box P is provided with valves Q R, the same as in my said application, and the box is of substantially the same construction as in my said application, except that it is formed with the side chamber, A, at the top and the opposite side chamber, B, at the bottom, in which the valve-operating,` rods S2 U2, chains (or other flexible connections) l B2, and the operating-wheels C C are placed. The rods S2 U2 are connected to the wheels by the said chains, and are operated by cords or wires S3 U3, the same as in my above-mentioned application. Each valve is provided with a CL (l.

oted arms E is weighted, as at E', to rapidly close the valves. The wheels C t" are pivoted parallel with the arms E, and each wheel is provided with a pin or stud, h,which projects under the adjacent arm and serves to lift it and the valve when the wheel is turned to carry the said pin above the axis of the wheel, as shown in Fig. 2. The operating-cord beinev relaxed, the valve will drop of its own weight, returningI the wheel and parts connected therewith.

By this construction all springs are avoided and the operating-rods, being connected tothe wheels by chains, will not be distorted in operation, but will pass always in a straight line through the boxes c at the tops of the side chambers, A I, thus obviating friction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The suction-box P, provided with valves, and wheels having,l pins engaging with projections on the valves, in combination with the operai ing-rods connected to the wheels by chains, substantially as described.

2. The suction-box P and valves pivoted therein and attached to the pivoted arms E, in combination with the operating-wheels provided with side projections to engage with the pivoted arms l, and the rods attached to the wheels by flexible connections, substantially as described.
